GEORGE M. \VELLS, OF NE\V YORK, N. Y. ASSIGNOR TO THE SOLIDITY IRON LAST COMPANY, OF SAME PLACE.

LAST.

SPECIPICATIOH forming part of Letters Patent No. 344,229, dated June 22, 1886.

Application filed June 6, 1881. Serial No. 35,017.

To all whom, it may concern:

Be it known that I, GEORGE M. WELLs, of New York, in the county and State of New York, have invented a new and useful 5 Improvement in Lasts; and I do hereby declare the same to be fully described in the following specification, reference being had to the accompanying drawings, of which Figure lis a perspective view of the block,

: and Fig. 2 of the body, of one of my improved lasts. Fig. 3 is a side view. Fig. 4 is a section on line z 2, Fig. 3. Figs. 5 and 6 are diagrams for illustration.

The block A is a shell with two tongues, a

IS a, fitting into a wide groove, 7), in the body B, thereby considerably reducing the weight of both the block and body, and yet having both abundantly strong. The upper portions of the heel part of the body B are omitted,

and consequently the curve of the groove I) and tongues a a may be such as to carry block A almost straight back toward the heel when it is withdrawn from body B.

Another feature of my invention consists 2 5 in making the bearing-surfaces of the dovetailed groove I) and the dovetailed projections a a at an angle with the surfaces of the body and block where they come into contact, so that the contact-surfirces, body, and block will 36 not bein contact until the block is pressed forward as far as it will go, the bearing-surfaces of the dovetailed projection and the groove acting as ways upon which the block slides -when it is put in place or removed from its place on the body. Heretofore the contactsnrfaces of the body and block were madesubstantially parallel with the bearing-surfaces of the groove and projection,and consequently the block was obliged to slide on the body 40 when the block was withdrawn or replaced,

while in a last embodying this part of my invention the sliding is confined to the bearingsurfaces of the groove and projection, the contact-surfaces of the body and block sep- 5 arating as soon asthe block is drawn back slightly on the ways formed by the bearing- (No model.)

surfaces of the groove and projection, as will be more clear from Figs. 5 and G of the drawings, which are diagrams for illustrating this part of my invention, and in which the dotted lines 00 :20 show the line upon which the block A travels on the ways formed by the bearing-surfaces of the groove and projection, and the full lines y illustrate the contact-sun faces between the body B and block A, and from which it will be seen that when block A is moved on the ways above mentioned, in the direction of the arrow, the points 1 2 3 4 in the block will move away from the correspond ing points in the body, (See Fig. 6, which shows theblock A moved slightly back.) This feature of my invention is especially important in cast-metal lasts wherethe body is cast upon the block, or vice versa, and the two parts are united by a dovetail, as in the last above described, but is applicable, of course, to all lasts in which the body and block are held together by a tongue and groove,and itgreatiy facilitates both putting the block in place preparatory for use, and also pullingthat is, withdrawingthe block from the body when the last is in a boot or shoe.

\Vhat I claim as my invention is l. A cast-metal lasthavingits block A made hollow or shell-1ike and provided with the tongues a a, and its body B provided with the wide groove I), to receive the tongues a a, as above described.

2. The block A, provided with the dovetailed projections a ct, whose under faces are at an angle with the bearing-surfaces of the block, in combination with body B, provided with the groove 1), whose bottom is at an angle with the bearing-surfaces of the body, the groove serving as a way in which the projections slide, substantially as and for the purpose set forth.
